Duplicated classes between different packages.

[pocorall]

object BuildInfo exists in both spire-platform_2.11-0.16.0.jar and spire-util_2.11-0.16.0.jar.

Classes in package spire.scalacompat exists in both spire-platform_2.11-0.16.2.jar and spire-util_2.11-0.16.2.jar.

This duplication prevents me to use R8 Android build tool.

I'm hitting this as well:

Did you ever figure out a fix @pocorall ?

@pierzchalski I am not using spire right now.
